Staff Product Designer (Grant OS)

Instrumentl is a profitable, hypergrowth, YC-backed SaaS platform building the operating system for grant-funded organizations. They are seeking a Staff Product Designer to own the design of GrantOS, leading the design across multiple product areas and driving product development in complex B2B environments.

Responsibilities:

• Own GrantOS end-to-end
• Lead design across GrantOS Platform and Core, from discovery and research through shipping and iteration
• Shape how grant professionals interact with Instrumentl as a platform: task management, reporting, integrations, and the data relationships that span the full grant lifecycle
• Drive zero-to-one product development in greenfield spaces where the problem isn't fully defined, and help define it
• Define the interaction patterns and design system foundations that every other product area inherits
• Raise the quality bar across Instrumentl's design system and coach other designers
• Act as a force multiplier for the broader design team, shaping how the org operates
• Conduct and synthesize user research independently, translating ambiguous user needs into clear product direction
• Partner as a true strategic peer to your PM and engineering lead, bringing a point of view and driving alignment across product, engineering, and GTM

Requirements:

• 8+ years of product design experience, with meaningful time at senior or staff level
• Proven track record owning complex B2B product areas end-to-end, including multi-entity workflows where data relationships, user roles, and cross-team collaboration intersect
• 0-to-1 product ownership: you've started from a problem rather than a spec, and made good calls under uncertainty
• Strong systems thinking and Figma/prototyping craft, deep involvement in user research from planning through synthesis, and the ability to influence product vision rather than just execute it
• B2B SaaS background, especially in complex or enterprise-adjacent systems
• Experience with agentic or AI-powered product surfaces, and already using AI tools in your design practice
• Design systems experience: defining patterns, not just using them
• Exposure to compliance, data integrity, or workflow-heavy domains
• Experience mentoring or coaching other designers
• Familiarity with the nonprofit or social impact sector
